Application filed April 2', 1900.

To all whom it may concern:

Be it known that I, GEORGE E. EVANS, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Cultivators; and I do hereby declare that the following is a full, clear, and exact descriptlon of the invention, which will enable others skilled in the art to which it 'appertains to make and use the same.

nature that the shovels swing in the arc of a circle and in consequence of that movement cannot produce the best results.

The pivotal connection from which the rear end of the shovel-beam is swung is the center from which the are is described, and the lowest position of the shovels isimrnediately beneath that connection. A movement of the shovelbeam at either side of the position mentioned will evidently change the working depth of the shovels. The work performed under these conditions is obviously unsatisfactory. By my improved construction 'I am enabled to move the shovels inahorizontal line, with the result that the work done is perfectly uniform regardless of the extent of lateral movement. I In addition to this my invention relates to certain details of construction and arrangement of parts more particularly point ed out in the claims;

In the appended drawings, Figure jl'is a perspective view ofthe cultivator. Fig. 21s a side elevation thereof, showing the portions necessary to make my invention under stood. Fig. 2 is a perspective view of a pivotal connection for the forward end of the shovel-beam. Fig. 3 is a side view of a crane i or other suitable device.

Serial No. 11,118. (No model.)

Figs. 3 and 4. Fig. 6 is a rear elevation of the arrangement shown in Fig. 3, indicated in various positions to clearly show the horizontal movement of the shovel-beam.

In the figures, A Aare the carrying-wheels, B the axle, and C the tongue.

D D are frame portions connected to the tongue near the forward end thereof. These serve to journal the axle by means of the boxings D.

The shovel-beams shown atE E are carried at their forward unturned ends H in pivotal yokes F. Said yokes are adapted to swing in a vertical plane on a rod G, secured to the tongue and frame, and their extremities are arranged to receive the said forward up-' turned ends of the said beams E E, upon which are collars J, adapted to engage with notched lugs 1, formed with said yokes to prevent separation of the parts. This arrangement allows the beam to swing in all direetions with perfectfreedom; but other means than this may of course be used.

The usual draft attachments and seat K andI respectively, areshown'inFig. l, the latter being hung from the rear extremities of the frame portions D. Plates M are securely bolted to the portions D, together with the boxings D, as shown in Fig. 4,-and virtually form part of the implement -frame. Said plates extend toward the middle of the ma chine, and on the free extremity of eachis mounted a standardof any desired construction that will'readily permit a free sidewise movement of a crane, consisting, preferably, of an arm or mast 0, having a sleeve P on its upper extremity. Such sleeve carried a rear wardly-projecting lug Q, having the forked extremity R of a similar sleeve S pivoted thereto. The latter sleeve loosely carries a rodTand is bifurcated 'to receive a collar T,

secured to such rod by means of a set-screw By this or kindred means free movement of said rod within the sleeveis permitted, but at the same time prevents its withdrawal therefrom. The lower extremity'of the rod is pivotally attached to beam from side to side for the purposes described. Since the beam E is pivoted at its forward end, a lateral movement at its rear 7 end will naturally turn the rod'T axially. Therefore by reason of the said rod having connection with the arm suitable means for allowing a swivel movement mustbe provided, andhence theeonstruction above described. I

The mast O operates after the manner of a crane and carries the shovel-beamwith ease and precision. I mayuse other methods than shown and described for carrying such mast, and I may provide other means than this for carrying the shovels in a horizontal. plane.
